Cycle indicator for fluid distribution systems

ABSTRACT

A cycle indicator is provided for monitoring movement of a fluid control piston of a divider block for a fluid distribution system. The cycle indicator connects to the divider block in a manner that allows fluid communication between the divider block and the cycle indicator. The cycle indicator includes a spring-biased piston follower that extends into the divider block through a housing so that movement of the fluid control piston is translated to the piston follower. The piston follower extends into the divider block through an opening in the housing. The opening is not sealed allowing fluid within the divider block cylinder to flow past the piston follower and into the housing. Since there is no relative movement between the seal and any moving part such as the piston follower fluid leakage is eliminated or at least substantially reduced. An internal magnet is coupled to the piston follower and activates an external magnet that provides a visual indication of the movement of the fluid control piston.
